Patented July 8, 1930 RICHARD PABST, GFWURZBURG, GERMANY HEATING DEVICE FOR THERAPEUTIC BATES Application filed April 18, 1929, Serial No. 356,029, and in Germany September 1, 1927.

This invention relates to heating devices, and the primary object of the invention is to provide a device of this character for heating the water or'liquid in therapeutic baths, the

invention more particularly relating to heating devices of that class wherein a heating coil is mounted adjacent to the receptacle contaming the bathing liquid and in such manner that it can be conveniently swung into and out of the bathing liquid.

An object of my invention is the \provision of a simply-constructed compact heating coil for the purpose referred to and in a manner as hereinafter set forth, which is constructed with a steam inlet pipe and a stealn outlet pipe, both arranged to constituteiswing arms whereby the coil can be swung bodily into and out of the contents of the bath receptacle.

For use with a heating medium such as high pressure steam and for use with a bathing liquid in which a gas, such for instance as carbonic acid gas, is employed as a therapeutic agent, the device of my invention is especially advantageous, owing to the simple compact arrangement which'permits the coil while the heating medium is passing therethrough to be intermittently swung into and out of the contents of the bath receptacle.

A. further object is the provision of a heating coil of the character described, capable of being mounted so it can be utilized for the eflective heating of the contents of two separate bath receptacles.

Other objects of the invention 'will appear The invention consists in the features of constructionand in the arrangement or arrangements of parts as hereinafter more fully described and as particularly pointed out in the subjoined claims.

The invention will be best understood by referring to the accompanying drawing,

forming a material part of this application,

and in which Figure 1 represents a cross section through two adjacent bath receptacles, showing n cross section and elevation the heating device of my invention;

. Figure '2 represents a top. plan of the coil with its connected swing arms; and

Figure 3 represents on a larger scale a fragmentary longitudinal section of the coupling piece incorporated in the coil.

The preferred form of construction, as illustrated in the accompanying dr awing,'comprises an endless coil consisting of outer lengths 10 and 11 connected at one end by a portion 12, and the inner lengths 13 and 14 connected at one end by a portion 15, the outer and inner lengths 10 and 13 being connected by a portion 16, while the outer and inner lengths 11 and 14 are connected by a portion 17. In this construction, it will be observed that the connected outer and inner lengths are in parallel relation so as to provide a com.- pact structure adapted to be swung into and out of the contents of a bath receptacle; and by preference as disclosed in Fig. 1 the coil structure in a transverse directionis somewhat curved with the inner lengths 13 and 14 representing the lowest portions thereof. The coil structure is reinforced and the lengths thereof held together in relationship by means of cross the desired members or hangers 18 and 19 which embrace the lengths like a hearing as illustrated by ample at 20in Fig. 3.

way of ex- Incorporated in one of the coils, herein shown to be the length 13, is a coupling piece which is indicated generally by the numeral 21 and which is disclosed as comprising the T fittings 22 and 23 connected by a pipe 24, this arrangement by preference being such that the end portions as 25, as best illustrated in Fig. 3, of the coil length 13 have turning fit in the T fittings. 22 and 23 are arms Joined to the T fittings 26 and 27 respectively,

which arms are in the form of pipe connections by which to support and as well to swing the coil structure as an ent axis member 28. One end, 29

ity about an of the axis member 28 is in the form of an inlet pipe or duct and through which-the steam passesto the arm 26 and thence to the coil.

The opposite arm 30 of the axis member 28 comprises an outlet pipe leaves the coil 29 of the axis member is any suitable source of steam sup opposite end 30 thereof is pipes or duct for the steam which through the arm 27 The end connected up with 1y, while the o a y itableline connection by means of which the steam may be discharged. In this manner provision'iIs made for supporting the coil structure by the pi e connections 26 and 27 from, the axis mem er 28, the pipe connection 26 with the end 29 constituting the connections through which the steam enters the coil while the pipe connection 27 with the end 30 constitute the parts through which the steam escapes from the coil after havin completed the circuit therein from the T tting 22 to the T fitting 23.

The axis member 28 is mounted for turning movement in an suitable bearings, for instance as by the earings 31 illustrated more or less diagrammatically in Fi 2. "As represented in Fig. 1, the heating device may be arranged so that it may be employed for heating the contents of two adjacent bath receptacles as 32 and 33. Preferably and as shown, the axis member 28 is suitably mounted for turning movement exteriorly of the re, ceptacles and at a central location with respect thereto so that the arms 26 and 27 can be used as means whereby to support the coil structure in either of the receptacles, the broken line 34 in Fig. 1 being indicative of the path of movement of the coil structure from its heating position in receptacle32 to its heating osition in the receptacle 33. The arms 26 and 2-7 are preferably of a length to the interiors of the receptacles, a coil carried at the outer ends of said arms to be swung therewith into and out of the'interiors of the receptacles, said turning means and arms being constructed and arranged to constitute inlet and outlet passages for said coil to provide a circulation through said coil.

support the coil structure adjacent the bottom of'the receptacle into which it is swung.

From the foregoing description taken in connection with the accompanying drawing, it will be manifest that I have disclosed an extremelysimple, compact, and thoroughly satisfactory form of construction which embodies the features of advantage enumerated in the statement of invention; andwhile I 1 have, in the present instance, illustrated and described the preferred embodiment thereof,

it is to be understood that the construction is susceptible of modification in various particulars without departing from the spirit or scope of my invention or sacrificing any of its advantages.

I claim: a

1. Incombination, two adjacent bath rearmsin the form ofpipe connections support- Y ing the coil from the axis member and constituting inlet and outlet passageways between said coil and said inlet and outlet ducts, re-' spectively, said arms being of alength to support said coil in either of'the bath recep tacles and adapted to swing said coil from one' bathreceptacle to the other. 2 In combination with two bath receptacles" turnin therefrom, said turning means being mounte outside the interiors of the receptacles-and said arms being swingable into and out of means and arms promoting
